Gce Model Questions Vol1 2021 Chemistry Question 23
Practice objective / multiple choice question 23 from the 2021 Gce Model Questions Vol1 Chemistry examination.
In acidic solution the redox reaction \(\ce{MnO4^- + Fe^{2+} -> Mn^{2+} + Fe^{3+}}\) occurs. Standard potentials are: \(\ce{MnO4^- + 8H+ + 5e- -> Mn^{2+} + 4H2O}\) \(E^\circ = +1.51\) V and \(\ce{Fe^{3+} + e- -> Fe^{2+}}\) \(E^\circ = +0.77\) V. If \([\ce{Fe^{2+}}] = 0.010\) M, \([\ce{Fe^{3+}}] = 0.10\) M and the pH is 2, calculate the cell potential at 25 °C.
